First person to answer correctly will be marked brainliest. A student observed the shape of the Moon once every 7 days during the month of June. Which of the following sets of drawings shows how the Moon’s shape could have changed during the month of June?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
